High efficiency distillation head



FIG. 1 is a right side elevational view of a high efficiency distillation head, according to the current disclosure.

FIG. 2 is a left side elevational view of a high efficiency distillation head, according to the current disclosure.

FIG. 3 is a front elevational view of a high efficiency distillation head, according to the current disclosure.

FIG. 4 is a rear elevational view of a high efficiency distillation head, according to the current disclosure.

FIG. 5 is a top plan view of a high efficiency distillation head, according to the current disclosure.

FIG. 6 is a bottom plan view of a high efficiency distillation head, according to the current disclosure; and,

FIG. 7 is a right side elevational view of a high efficiency distillation head sitting on a round-bottom flanged flask, and an open bottom design of the high efficiency distillation head attached to the round-bottom flanged flask, according to the current disclosure. The round-bottom flanged flask is not part of the claimed design.

The dashed broken lines shown in the figures represent portions of the distillation head that form no part of the claimed design. The internal elements of the distillation head, which can be seen through the exterior of the high efficiency distillation head in some embodiments, do not form part of the claimed design.

The dot-dash cross-hatching shown in the drawings represent an opaque surface of the high efficiency distillation head. 

CLAIM The ornamental design for a high efficiency distillation head, as shown and described.
